Elton John has postponed his summer tour after being diagnosed with an abscess of the appendix, according to the Vintage Vinyl News. His spokesman said in a statement "Following a number of exploratory scans and blood tests with his medical team in the UK, a diagnosis of appendix abscess surrounding retrocaecal appendicitis has been confirmed. Sir Elton is currently undergoing a course of intensive antibiotics and is expected to undergo surgery in the UK in the coming weeks, once doctors can be confident they have sufficiently reduced toxins within the inflamed appendicitis site."

The statement went on to say: "Elton is incredibly disappointed to postpone these tour dates. To know that he made such super-human efforts and continued to perform to thousands through his illness only confirms his dedication to his European fans. He is eager to be back on top form and return to play the remaining shows starting in early September 2013."

As it stands now, Elton John's next show is set for September 4th in Leeds, England at First Direct Arena.

He'll kick off his North American dates on September 18th with the opening night of his latest run at Las Vegas' Colosseum At Caesars Palace.
